you should have dhamma wheel up on your screen! but what opinion would you like shared?

This offering maybe right, or wrong, but it is one, the other, both, or neither!Blog,-Some Suttas Translated,Ajahn Chah."Others will misconstrue reality due to their personal perspectives, doggedly holding onto and not easily discarding them; We shall not misconstrue reality due to our own personal perspectives, nor doggedly holding onto them, but will discard them easily. This effacement shall be done."

at the end of the day if they are in the best place to remind you of the Buddha, Dhamma & Sangha they are in the right place.

personally I like the one on your tower, not a fan of sparckly rupas prefering plain ones, but it looks realistic and that is what I like about it.

I like them both, but prefer the Thai sparklie one. The other has a more Mahayana type look, imo, with the wider body. The sparklie one has the robes with one shoulder off, so appears to definitely be Theravada, but they are all symbols so the other is good too.

I would put the Thai looking one in a slightly safer place. Perhaps still on the tower, but on a small cloth, instead of books. But it is up to you, of course.

“No lists of things to be done. The day providential to itself. The hour. There is no later. This is later. All things of grace and beauty such that one holds them to one's heart have a common provenance in pain. Their birth in grief and ashes.” - Cormac McCarthy, The Road

Both 2 rupas are nice. Not sure if the sparklie one is a Thai one, because the robe with flowers all over seems odd to me!

My humble suggestion (perhaps somewhat conservative/orthodox): Re-arrange the shelf in your bedroom, above the triangular niche, and place the sparklie there. It's safer than to place it on top of your PC tower, and its place is also at a higher, more respectful position.
